Shared Numbers with Call Forwarding

Drop Cowboy maintains a shared pool of phone numbers available to all Drop Cowboy customers to use.

We will pick a caller_id from our shared number pool that closely matches the target contact’s geographical location based on the following criteria:

  • If postal_code is contained in the API request, we will select a caller ID nearest to the contact's postal code.

  • If postal_code is omitted, we will select a caller ID nearest to the contact's area code based on the contact's phone number.

  • If no match is found based on postal code or phone area code, then we will select a random caller_id from the number pool within the contact's country.


When the contact returns a call to the caller ID phone number, we will forward the call to whatever phone number you specify in the forwarding_number or send the call to your Drop Cowboy IVR that you specify in the phone_ivr_id property of your RVM API request.
